Answer: It is difficult to be sure about the accuracy of the 68% reported by Yearn's API. The best way to get a definitive answer is to ask Yearn directly. However, it is important to consider the context of the reported data. For example, if the 68% is based on a survey or research project that was conducted in a particular region, it may not be reflective of the global situation. Additionally, it is important to consider the timeframe in which the data was collected. If the data is from a few years ago, it may not be reflective of the current situation. Finally, it is important to consider the source of the data and the methodology used to collect it. If the data was collected using a reliable and unbiased method, it is more likely to be accurate. Ultimately, asking Yearn directly is the best way to get a definitive answer.
